Electrical stimulation of the caudal medullary raphe in cats decreased inferior cardiac and renal sympathetic activities but increased vertebral sympathetic activity.
Electrical stimulation of the caudal medullary raphe produces differential sympathetic outflow patterns to cardiac, renal, and vertebral nerves in a feline model.
No takes yet. Share an insight, caveat, or question.
Differential sympathetic responses in cats suggest central selectivity; leaves open translation to human autonomic therapies.
Larsen et al. (2000) studied this question. Electrical stimulation of the medullary raphe was evaluated on Changes in inferior cardiac (CN), vertebral (VN), and renal (RN) sympathetic nerve activities. Electrical stimulation of the caudal medullary raphe in cats decreased inferior cardiac and renal sympathetic activities but increased vertebral sympathetic activity.
